BRIEF DESCRIPTION OF THE DRAWINGS
Detailed description will be given below in conjunction with accompanying drawings, in which:
FIG. 1 is a cross-sectional view of a plug valve for a gas stove of an exemplary embodiment of the invention;
FIG. 2 is another cross-sectional view of a plug valve for a gas stove of an exemplary embodiment of the invention;
FIG. 3 illustrates a closed state of a cock of the invention; and
FIG. 4 illustrates an opening state of a cock of the invention.
 DETAILED DESCRIPTION OF THE EMBODIMENTS
As shown in FIGS. 1 and 2, a plug valve for a gas stove of the invention comprises a natural-gas nozzle 1, a propane-gas nozzle 2, a valve body 3, a cock 4, an adjusting rod 5, an O-shaped ring 6, a stop ring 7, a spring 8, a stop plate 9, a cover 10, a pair of screws 11, and a valve rod 12.
The adjusting rod 5, the O-shaped ring 6, and the stop ring 7 are disposed in the cock 4.
The cock 4, the spring 8, the stop plate 9, the cover 10, and the valve rod 12 are disposed in the valve body 3 via the screws 11, and the natural-gas nozzle 1 or the propane-gas nozzle 2 is disposed in the valve body 3.
The cock 4 is screw fit with the adjusting rod 5, and displacement of the adjusting rod 5 with respect to the cock 4 is limited by the stop ring 7.
A first slot is disposed on the cock 4 and operates to fix the stop ring 7 (not shown).
The natural-gas nozzle 1 is used when the gas is natural gas, and flow variation of natural gas is implemented by turning the valve rod.
The propane-gas nozzle 2 is used when the gas is propane gas, and flow variation of propane gas is implemented by turning the valve rod.
The cock 4 and the adjusting rod 5 are radially fixed via the O-shaped ring 6.
A second slot is disposed on the adjusting rod 5 (not shown) and operates to fix the O-shape ring 6.
A nozzle hole of the natural-gas nozzle 1 is larger than that of the propane-gas nozzle 2.
As shown in FIG. 4, as natural gas is used, at low setting the adjusting rod 5 is turned via a screw driver so that it is in an opening state. At this time holes B and D are connected with each other whereby increasing low-level flow of natural gas. At high setting, the propane-gas nozzle 2 is replaced by the natural-gas nozzle 1 whereby increasing high-level flow of natural gas.
As shown in FIG. 3, as propane gas is used, the adjusting rod 5 is turned via a screw driver so that it is in a closed state. At this time the natural-gas nozzle 1 is replaced by the propane-gas nozzle 2. The adjusting process is very convenient and reliable.
The operation principle and the flow direction of the plug of the invention are as follows:
When propane gas is used, the valve rod 12 is turned and drives the cock 4 to rotate for 90 degrees in a counterclockwise direction to reach a high-level position. At this time, propane gas enters via an air inlet and a hole A, and is discharged via a hole E of the propane-gas nozzle 2. If the cock 4 continues to rotate for 90 to 180 degrees, a low-level position is reached. At this time, propane gas enters via the air inlet, and is discharged via holes C to E.
When natural gas is used, the valve rod 12 is turned and drives the cock 4 to rotate for 90 degrees in a counterclockwise direction to reach a high-level position. At this time, natural gas enters via an air inlet and a hole A, and is discharged via a hole F of the natural-gas nozzle 1. If the cock 4 continues to rotate for 90 to 180 degrees, a low-level position is reached. At this time, natural gas enters via the air inlet, and is discharged via holes C and D (or B) to F.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
